Creeping along the jungle paths through the spotlights of sun filtering down through the canopy, careful not to tread on an army of marching ants, your nature guide will point out plants and insects and the fascinating symbiosis between them. He might take you through the territory of the crested owls or spider monkeys, expertly mimicking the creatures’ call to win their trust and coax them out of hiding. When darkness falls, have your flashlight ready to spot creatures of the night, from tarantulas and boas to stick insects and frogs.
